Problems solved by technology

[0002] Existing commonly used flame-retardant plastic foaming materials, its composition includes ethylene-vinyl acetate copolymer, high-pressure low-density polyethylene, low-pressure high-density polyethylene, high-low pressure composite polyethylene and flame retardants, chemical additives, volcanic ash and kaolin Filling materials, etc. Although products foamed with these materials also have good flame retardant function and environmental protection effect, their compressive and flexural performance fails to meet the highest standards, which limits the scope of application.
At present, plastic foam boards (flame retardant or not) often have the following defects: First, the compressive and flexural effects cannot meet the highest standards
[0003] It can be known from the above examples that the lack of high compressive and flexural properties severely limits the application of flame-retardant plastic foam materials. Therefore, if a flame-retardant plastic foam material that is compressive and flexural can be developed, this material will be greatly expanded For example, it can replace cement, bricks, bamboo boards and even some steel, so it is a good protection and conservation of resources, which has great and far-reaching significance

Abstract

The invention discloses a compression-resistant fracture-resistant and flame-retardant plastic foaming material and a preparation process thereof. The material comprises the following components in parts by mass: 6-6.5 parts of plastic, 1-1.5 parts of cerium metal powder, 2-3 parts of volcanic ash, 2.5-3.5 parts of a flame retardant and 0.5-1 part of a chemical assistant. As the foaming material adopts the cerium metal powder, the use of the flame retardant is reduced, the foaming material is more environment-friendly and efficient while the cost is lowered, the compression resistance and fracture resistance of the plastic are improved, and an application scope of the foaming material is extended.
